feshop, a notorious dark web marketplace, sources its SSN dumps through illicit means, primarily involving data breaches and cybercrime activities. These dumps typically contain stolen Social Security Numbers (SSNs) along with other personally identifiable information (PII), such as names, addresses, and dates of birth. The data is often harvested from unauthorized access to databases, phishing scams, malware infections, and other illegal activities that compromise personal information 

Once obtained, this stolen data is packaged and sold to criminals who use it for various fraudulent activities, including identity theft and financial fraud. Feshop markets these SSN dumps as "high-quality" and "fresh," but the accuracy and reliability of the data are highly questionable. The information may be outdated, incomplete, or even fabricated, leading to significant risks for those whose data is compromised ​.

Engaging with platforms like Feshop is illegal and exposes individuals to severe legal consequences, including criminal charges and financial penalties. Moreover, using such stolen data can contribute to further criminal activities and cause harm to the victims whose information has been compromised.
